THREAD GUIDE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 293,402, dated February 12, 1884.

To all whom it may concern:

Be-it known that 1, JOHN H. H. BENNETT, of Springfield, in the county of Sangamon and State of Illinois, have inventedadevice (here tofore, with my knowledge or consent, upatented anywhere) for controlling the thread in the thread-bearing parts of needle-bars, takeup levers, and check-levers of sewing-Ina chines, of which the following is a full, clear,-

' or over the slack-thread take-up on the one die-bar on the other side.

side nor over and around the top of the nee- The thread is so confined without being pressed in a groove turning at right angles that it will not flyfrom side to side through the bar, giving too much slack thread on either side.

Figure 1, a side view of a needle-bar, represents any slot, A, through which the thread is laid into the threadhole H, at the bottom of which is aflat thread-groove, B. Not shown in the other figures, though intended for all.) I

I Application filed June 28, 1883. (No model.)

Fig. 2, a needle-bar, and Fig. 4E, acheck-lever, represent spool-shaped checks 0 C, placed it. The depth of the thread-groove B under the check 0 is such'that the thread, though it may be closely confined, is not pressed bythe check, the flanges of which, bearing the thread downward on both sides of the bar or lever, prevent it from passing too freely through from side to side, thus controlling the amount of slack thread on either side.

What I claim is In a sewingmachine, the check-lever or needle-bar used as a thread-carrier, in combination with the slot A, the check 0, the flanges F F, and the thread-groove 13, under the check 0, substantially as described, and for the purpose set forth.
